In the existing container spreader, a ratchet, a gear, and a crank link are used to drive the rotation of the lock. The spreader is provided with a thin steel wire rope that does not bear the weight of the container, and a tension spring is connected to the lower end. When the door hoist is lifted, the tension spring at the lower end of the thin steel wire rope drives the ratchet wheel in the middle part of the frame to rotate, the ratchet wheel drives the transmission shaft, and the rotation lock is rotated by 90° each time through the connecting rod and the crank to realize the combination of the spreader and the container or The deficiencies are: 1. If a rotary lock is stuck, it will cause the crank linkage to malfunction.
2. Since the spreader has no legs, when it is placed on the ground, the corner lock without the guard plate directly touches the ground. When lifting, the corner lock should be rotated 90° on the ground, the friction is large, and the lock head is easily damaged.
3. Because the tension spring is stressed, the tension spring head is easily damaged.
The purpose of the utility model is to provide a container spreader which is driven by a lifting sling to rotate the rotary lock. The spreader has the function of turning the lock display and automatically locking the turn lock after the spreader and the container are detached.
The technical solution of the utility model is that the container spreader thus realized is composed of a turn lock mechanism, a lock mechanism, a display mechanism, a frame and a sling.
The rotation lock mechanism is composed of a rotary lock, a spindle nut, a spindle cover, a directional sleeve, a guide sleeve and a tie rod. The guide sleeve, the spindle nut, the spindle cover and the directional sleeve are all mounted on the rotation lock shaft, and the pull rod is installed between the guide sleeve and the rotation lock shaft. The rotary lock shaft has symmetric spiral grooves on both sides, a cross groove on the upper end, and a thread on the rotation lock shaft; a cylindrical pin on the upper plane of the pull rod tray, and a cylinder on the same circumference on the lower plane of the pull rod tray Pin; the upper end of the guide sleeve is provided with a hole that cooperates with the pull rod tray.
The locking mechanism consists of a lock plate, a ram and a sleeve. The lock plate is mounted on the pin at the rear end of the hanger. The ram is mounted in the sleeve and has a buffer spring at the lower end of the ram.
The display mechanism is composed of a display panel, a rib, a rotating shaft, a head, a support and a push rod, a fixing sleeve, a spring and a cam. The cam is mounted on the rotary lock shaft and is fixedly mounted on the main sleeve. The spring is mounted in a fixed sleeve with a push rod inserted into the spring. One end of the push rod is in contact with the cam and the other end is in contact with the plug. The rotating shaft of the display panel is inserted into the support, and the support is fixed on the frame.
The frame has a hanging seat, a guard plate and a supporting leg. The main corner of the frame has a main sleeve, and the main sleeve is provided with a rotation locking mechanism, and the inner side of the frame has a diagonal beam. There are load-bearing plates between the inclined beam and the side beam and the main sleeve. There are ears on the load-bearing plate, and the hanger is mounted on the lugs through the pin. The sling is composed of a vertical plate, a pressure plate, a spring seat and a tailstock. The tailstock of the sling is connected to the tie rod. The rear end of the hanger is connected to the sling and the lock plate via a pin. The side of the frame has legs which can be rotated by 90°. One end of the chain is fixed to the leg panel and the other end is attached to the pin. The pin can fix the leg in a horizontal or vertical position parallel to the frame.
